Making Programs Faster

The Missing 15%

A couple of years later, some bright boy finally asked the right question
He did not compare the new syntax with the old syntax in Perl 5.005
Instead, he compared the old syntax in 5.005 with the old syntax in 5.004
5.005 was 15% slower
Adding the pseudohash stuff to 5.005 had slowed down all hash access by 15%
In the best possible case, the efficiency gain was just enough to get you back to zero
Pseudo-hashes are now being withdrawn
Good riddance
